Where Claude Fable 5.1 still wins
Fable is built for long-form generation and nuance. If the output is prose a person will read, the comparison is not price — Jev has no output to compare.
The honest caveat
This compares price, not accuracy. A model that is 100x cheaper and wrong 5% more often can easily be the more expensive choice once you price the mistakes. Jev returns a calibrated probability with every answer, so the practical move is to route the confident cases automatically and send the rest to Claude Fable 5.1 or a human — which makes this a routing decision rather than a replacement decision.
